A3 rom source modified to ca65 compatible format.
Source taken from the A3 level 2 service manual rom source listing.

Three modules:
diskio.s
saratests.s
monitor.s

1. Compile the three source files
ca65 diskio.s -l diskio.lst
ca65 saratests.s -l saratests.lst
ca65 monitor.s -l monitor.lst

2. Link the three modules together to make the rom image.
ld65 diskio.o saratests.o monitor.o -o a3rom.bin -C apple3rom.cfg -m apple3rom.map


Other files included:
source differences.txt - this lists the changes made to the source to make the rom match the dump I took from my Apple3 rom.
a3rom_dumped.bin - this was read from the rom from my A3 via an eprom reader.
